A process for the preparation of methane from gas mixtures containing hydrogen and/or steam and at least 5% by volume of carbonmonoxide by means of a nickel catalyst, which contains on a thermally stable oxidic carrier metallic nickel particles as an active catalyst component, in which the metallic nickel particles are chemically bonded to the thermally stable carrier. The chemical bond between the metallic nickel particles and the carrier is preferably provided by an interfacial layer different from the oxidic carrier, which layer consists of a compound containing oxygen and at feast one member selected from the group consisting of nickel and the carrier base element or elements. |
